How Much Caffeine in a Cup of Coffee? A Detailed Guide
In terms of caffeine intake, coffee is the most common food source. An average cup of coffee will provide you with around 95 mg of caffeine on average. However, the quantity of caffeine in different coffee drinks varies, and can vary anywhere from practically nothing to more than 500 mg per cup. This is a comprehensive guide on the caffeine level of various types and brands of coffee, including espresso.
What Factors Affect Caffeine Content?
The caffeine concentration in coffee is determined by a variety of factors, including:
- Coffee bean types: There are many distinct varieties of coffee beans available, each of which may naturally have a varying quantity of caffeine. Roasting: Lighter roasts contain more caffeine than darker roasts, despite the fact that darker roasts offer a more complex flavor. Type of coffee: The caffeine level of various types of coffee, including conventional brewed coffee, espresso, instant coffee, and decaf coffee, can differ greatly. Serving size: The volume of “one cup of coffee” can range from 30–700 mL (1–24 oz), which has a significant impact on the overall caffeine level.
Bottom Line: The amount of caffeine in a cup of coffee is determined by the type of coffee bean used, the roast style used, how the coffee is made, and the serving size.
How Much Caffeine Is in a Cup of Coffee?
The sort of coffee you consume is the most important factor in determining its caffeine concentration.
Brewed Coffee
In the United States and Europe, brewing is the most frequent method of preparing coffee. The process of brewing coffee, also referred to as regular coffee, involves pouring hot or boiling water over ground coffee beans, which are typically contained in a filter. One cup of freshly brewed coffee (8 oz) contains approximately 70–140 mg of caffeine, or an average of 95 mg per cup ( 1 ,2).
Espresso
Using a modest amount of hot water or steam, espresso is created by pressing the beans through a finely ground coffee grinder. Despite the fact that espresso has more caffeine per volume than normal coffee, it often contains less caffeine per serving due to the fact that espresso portions are typically tiny. A single shot of espresso is typically 30–50 mL (1–1.75 oz) in volume and contains around 63 mg of caffeine ( 3 ). As a result, a double shot of espresso contains around 125 milligrams of caffeine.
Espresso-Based Drinks
Many popular coffee beverages are produced by combining espresso shots with a variety of milk kinds and quantities in various proportions. Lattes, cappuccinos, macchiatos, and Americanos are examples of such beverages. Because the milk does not include any extra caffeine, the caffeine content of these beverages is the same as that of a cup of plain espresso. A single (small) cup of coffee has around 63 mg of caffeine on average, whereas a double (large) cup contains approximately 125 mg.
Instant Coffee
Instant coffee is created from brewed coffee that has been freeze-dried or spray-dried, and it is available in many flavors. It is often found in huge, dry chunks that disintegrate when exposed to water. The simplest way to make instant coffee is to combine one or two tablespoons of ground coffee with hot water. There is no need to prepare any beverages. Caffeine content in instant coffee is often lower than that of normal coffee, with one cup containing around 30–90 mg of caffeine ( 4 ).
Decaf Coffee
However, despite the fact that the name implies otherwise, decaf coffee does not contain zero caffeine. This beverage can include variable quantities of caffeine, with the average cup holding 3 mg. The caffeine content can range from 0–7 mg per cup, with the lowest cup containing 0 mg ( 5 , 6 , 7 ). However, depending on the kind of coffee, the technique of decaffeination used, and the size of the cup, some variations may have even greater levels of caffeine than others.
The bottom line is this: The typical caffeine level of an 8-ounce cup of freshly brewed coffee is 95 milligrams (mg). A single espresso or espresso-based drink has 63 mg of caffeine, whereas decaffeinated coffee contains around 3 mg (on average).
Are Commercial Brands More Caffeinated?
The caffeine content of some commercial coffee brands may be higher than that of conventional, home-brewed coffee. Coffee shops are especially well-known for serving huge cups of coffee, which may be as much as 700 mL in size (24 oz). The amount of coffee included in such cups is approximately the same as 3–5 regular-sized cups of espresso.
Starbucks
Starbucks is, without a doubt, the most well-known coffee establishment in the entire globe. It also serves some of the most highly caffeinated coffee available on the market. The caffeine concentration of brewed coffee at Starbucks is as follows (8,9): caffeine content:
- 180 mg for a short (8 oz)
- 260 mg for a tall (12 oz)
- 315 mg for a grande (16 oz)
- 415 mg for a venti (20 oz).
In addition, one shot of espresso at Starbucks has 75 milligrams of caffeine, which is considered moderate. As a result, all small espresso-based beverages include 75 milligrams of caffeine per serving. This comprises beverages such as lattes, cappuccinos, macchiatos, and Americanos, among other things (10). Larger versions (16 oz), which are created with two or three espresso shots (16 oz), also include 150 or 225 mg of caffeine, depending on the size. Starbucks decaf coffee has 15–30 mg of caffeine per cup, depending on the size of the cup.
The caffeine content of a single espresso and espresso-based beverages is 75 mg, but an 8-ounce cup of decaf coffee contains around 15 mg of caffeine.
McDonald’s
Almost everywhere in the globe, McDonald’s offers coffee under the McCafe brand; the company also sells tea. Even though they are a major fast food corporation that sells coffee, they do not standardize or quantify the amount of caffeine in their beverages. According to our calculations, the caffeine concentration of their brewed coffee is around (11):
- A small (12 oz) serving has 109 mg of sodium
- A medium (16 oz) serving has 145 mg of sodium
- A large (21–24 oz) serving has 180 mg of sodium.
Its espresso includes 71 mg of caffeine per serving, while its decaf contains 8–14 mg, depending on how big a cup you have. The bottom line is that McDonald’s does not standardize the quantity of caffeine contained in its coffee beverages. According to our calculations, a small cup of freshly brewed coffee has 109 mg of caffeine. Espresso has around 71 mg of caffeine, whereas decaf includes approximately 8 mg.
Dunkin Donuts
Dunkin Donuts is another another coffee and doughnut store business that is extremely popular all over the world. It has the following amount of caffeine (12) in their freshly brewed coffee:
- 215 mg for small (10 oz)
- 302 mg for medium (16 oz)
- 431 mg for large (20 oz)
- And 517 mg for extra large (24 oz).
One of their espresso shots has 75 mg of caffeine, which is also the amount of caffeine you can anticipate to get from one of their espresso-based beverages. The decaf coffee served at Dunkin Donuts may also contain a significant amount of caffeine. According to one source, a small cup (10 oz) of coffee has 53 mg of caffeine, while a large cup (24 oz) contains 128 mg of caffeine (13). That’s nearly as much caffeine as you’ll get in most other types of normal coffee, if not more.
A small cup of Dunkin Donuts coffee has 215 mg of caffeine, whereas a single espresso contains 75 mg. The bottom line: Incredibly, their decaf coffee may contain as much as 53-128 mg of caffeine, depending on the kind.
Is Caffeine Something to Worry About?
Coffee is abundant in antioxidants, and several studies have shown that coffee is beneficial to one’s health. Getting too much coffee, on the other hand, has been related to negative side effects such as anxiety, sleep interruptions, heart palpitations, and restlessness ( 14 , 15 ). Caffeine consumption of 400–600 mg/day is typically not related with any negative effects in the majority of persons. This equates to around 6 mg per kilogram (3 mg per pound) of body weight, or 4–6 typical cups of coffee per day ( 16 ).
Some people are extremely sensitive to it, while others are completely unaffected by enormous doses of it.
It’s simply a matter of trial and error to determine the appropriate amount.

Caffeine: How much is too much?
Caffeine has many advantages, but it can also cause issues. Learn how much is too much and whether or not you need to reduce your usage. Staff at the Mayo Clinic If you rely on coffee to get you out of bed in the morning and keep you going throughout the day, you are not alone. Every day, millions of individuals rely on coffee to keep them awake and increase their attention levels.
How much is too much?
Most healthy persons appear to be able to consume up to 400 milligrams (mg) of caffeine per day without experiencing any adverse effects. Approximately the amount of caffeine contained in four cups of freshly ground coffee, 10 cans of cola, or two “energy shot” beverages. You should keep in mind that the actual amount of caffeine contained in beverages varies greatly, particularly among energy drinks. The Food and Drug Administration of the United States has warned that caffeine consumed in powder or liquid form can result in hazardous quantities of caffeine.
- Such high doses of caffeine can result in major health concerns, and even death, if not treated promptly.
- A warning should be sent to adolescents and young adults about excessive caffeine consumption as well as the dangers of combining caffeine with alcohol and other substances.
- Even in adults, excessive caffeine use might result in undesirable side effects.
- Continue reading to find out if you should cut back on your coffee intake.
You drink more than 4 cups of coffee a day
If you’re consuming more than 4 cups of caffeinated coffee a day (or the equivalent) and experiencing negative effects such as the following, you might consider cutting back.
- Headache, insomnia, nervousness, irritability, frequent urination or difficulty to regulate urine, rapid heartbeat, muscle tremors, and other symptoms
Even a little makes you jittery
People react differently to caffeine depending on their genetic make-up. If you’re sensitive to the effects of caffeine, even tiny doses might cause unpleasant side effects such as restlessness and sleep issues in vulnerable individuals. The amount of caffeine you’re accustomed to consuming may have an impact on how you react to caffeine in general. People who do not routinely use caffeine are more susceptible to its effects than those who do.
You’re not getting enough sleep
Even in the afternoon, caffeine might have a negative impact on your sleep. Even little sleep deprivation can accumulate over time and impair your ability to stay alert and function well during the day. Caffeine use to alleviate sleep deprivation can lead to a vicious cycle of overindulgence.
Drinking caffeinated beverages, for example, may be necessary if you are having difficulty staying awake during the workday. However, the caffeine prevents you from falling asleep at night, resulting in you sleeping for a shorter period of time.
You’re taking medications or supplements
There may be an interaction between caffeine and some drugs and herbal supplements. Examples include the following:
- Ephedrine. This medicine, which is found in decongestants, may raise your risk of high blood pressure, heart attack, stroke, or seizure if you combine it with caffeine. This medicine, which is used to open up the bronchial airways, has been shown to produce caffeine-like effects in some people. Because of this, consuming Echinacea with caffeine may exacerbate the negative effects of caffeine, such as nausea and heart palpitations
- Echinacea is a natural antibiotic. This herbal supplement, which is sometimes used to treat colds or other infections, may raise the concentration of caffeine in your blood, which may exacerbate the unpleasant effects of caffeine
- Nevertheless, it is not recommended.
Consult with your doctor or pharmacist to determine whether caffeine may have an impact on your medicines.
Curbing your caffeine habit
Cutting back on caffeine may be difficult, whether it’s for one of the reasons listed above or simply because you want to save money on coffee beverages. Withdrawal symptoms such as headaches, weariness, irritability, and trouble concentrating on activities may occur if caffeine intake is reduced abruptly or stopped altogether. Fortunately, these symptoms are often moderate and subside within a few days of the onset. Try the following strategies to break your coffee addiction:
- Keep an eye on things. Start keeping track of how much caffeine you’re consuming through foods and beverages, especially energy drinks. Pay close attention to the labeling. However, keep in mind that your estimate may be a bit low because certain foods or beverages that contain caffeine are not included on the label
- Reduce the amount of time you spend on it gradually. Drinking one fewer can of soda or one fewer cup of coffee each day, for example, will help you lose weight. Alternatively, refrain from consuming caffeinated beverages late in the day. This will assist your body in becoming used to the reduced levels of caffeine and will reduce the likelihood of experiencing withdrawal symptoms. Make the switch to decaf. The majority of decaffeinated beverages have a similar appearance and flavor to their caffeinated counterparts. Reduce the brewing time or switch to herbal tea. When brewing tea, brew it for a shorter period of time. Its caffeine level is reduced as a result of this. Alternatively, look for herbal teas that are caffeine-free
- Check the label. Caffeine is found in several over-the-counter pain medications, but not all of them. Instead, look for pain medicines that are caffeine-free.
The bottom line
When it comes to grownups, caffeine is likely to be a part of their daily routine. Generally speaking, it will not cause any health problems. However, be aware of the potential adverse effects of caffeine and be prepared to reduce your intake if required.

How much caffeine in a cup of coffee: Types, brands, and other sources
Coffee is a popular beverage that contains caffeine, and it is arguably the most prevalent source of caffeine. The amount of caffeine in a cup of coffee can vary significantly based on a number of factors, including the kind of coffee, the brewing technique, and the manufacturer. Caffeine-containing foods and beverages are consumed by more than 95 percent of individuals in the United States, according to the Dietary Guidelines for Americans 2015–2020. Adults in the United States consume between 110 and 260 milligrams (mg) of caffeine on a daily basis on average.
In this post, we’ll look at the caffeine concentration of a variety of different coffee kinds and brands to see how they compare.
There are many different sorts of coffee, each with its own quantity of caffeine. We’ll go through the caffeine concentration of some of the most popular forms of coffee in the next section:
Brewed coffee
Brew coffee, also known as filter coffee, is made by steeping ground coffee beans in hot water for an extended period of time. A paper, metal, or plastic filter is used to separate the grounds from the brewed coffee, and this combination is often used for this purpose. A multitude of methods exist for brewing coffee, the most common of which are the use of filters, percolators, and French presses. A average 8-ounce cup of freshly brewed coffee has around 95 milligrams of caffeine.
Decaffeinated brewed
Despite its decaffeinated or decaf designation, coffee still contains a small amount of caffeine. For example, an 8-ounce cup of freshly brewed decaf coffee has around 2 mg of caffeine on average.
Cold brew
Cold brew coffee is distinct from iced coffee, which is merely the process of pouring brewed coffee over crushed ice. The coffee grounds are steeped in water at room temperature for anywhere between 8 and 24 hours in order to prepare cold brew coffee, according to the maker. According to a research conducted in 2017, a 12-ounce cup of cold brew coffee might contain anywhere between 153 mg and 238 mg of caffeine.
Instant coffee
Making this sort of coffee includes combining hot water with instant coffee powder or granules and brewing the mixture. Generally speaking, instant coffee has less caffeine than freshly brewed coffee. Approximately 62 mg of caffeine is contained in a normal 8-ounce cup of standard instant coffee.
Espresso
A powerful coffee beverage made by pushing hot water or steam through very fine coffee grinds, espresso is a popular choice among coffee enthusiasts. If you want to make espresso coffee at home, you may use a machine or a stovetop moka pot. Because of the strong caffeine concentration of espresso, serving portions are typically substantially less than those of brewed coffee. Approximately 63 milligrams of caffeine are included in a single 1-ounce shot of espresso. Many coffee producers and chain restaurants publish estimates of the amount of caffeine contained in their coffee products on their websites.
Dunkin’ Donuts
Dukkin’ Donuts is a well-known coffee and doughnut business that offers a broad variety of caffeinated drinks to its customers. In accordance with the website Caffeine Informer, one medium cup (14 oz) of several of the coffee beverages available at Dunkin’ Donuts contains the following amount of caffeine:
- Brewed coffee has 210 mg of caffeine
- Decaf brewed coffee contains 10 mg of caffeine
- An Americano contains 249 mg of caffeine
- A cold brew contains 260 mg of caffeine
- And a latte contains 119 mg of caffeine.
A single shot of espresso has 85 mg of caffeine.
Seattle’s Best
Retail storefronts and drive-thrus operated by Seattle’s Best Coffee, as well as several fast-food restaurants including Subway and Burger King, carry the company’s coffee goods. A small cup (12 oz) of several of this company’s coffee products provides the following amount of caffeine, according to Caffeine Informer:
- Brew coffee has 260 mg of caffeine
- Latte contains 75 mg of caffeine for both traditional and flavored variations
- Mocha contains 80 mg of caffeine.
The caffeine content of a single shot of Seattle’s Best espresso is 75 milligrams.
Starbucks
Starbucks is one of the most well-known coffee brands in the world. Starbucks is headquartered in Seattle, Washington.
The caffeine level of the company’s coffee products, as well as other nutritional information, may be found in their online beverages menu. For example, certain Starbucks beverages have as much caffeine as the following in an 8-ounce tall cup (12-ounce serving):
- Pike Place roast: 235 mg
- Decaf Pike Place roast: 20 mg
- Cold brew with cold foam: 155 mg
- Caramel macchiato: 75 mg
- Cappuccino: 75 mg

A number of factors influence the amount of caffeine present in a cup of coffee. The kind of coffee bean is one of the most important considerations. There are many distinct kinds of coffee plant, and the caffeine level of coffee beans derived from different plants varies as a result. The following are the two most common species of plant used in the production of coffee beans:
- Coffea arabica, sometimes known as Arabica, is a kind of coffee grown in Africa. Coffea canephora, also known as Robusta coffee, is a variety of the coffee plant.
According to a research conducted in 2016, Robusta coffee beans generally have around double the amount of caffeine found in Arabica coffee beans. The researchers discovered that Arabica beans have 34.1–38.5 g of caffeine per kilogram (kg) of dry coffee, but Robusta beans contain 68.6–81.6 g of caffeine per kilogram (kg) of dry coffee, according to their findings. A number of other factors can influence the quantity of caffeine in a cup of coffee, including but not limited to:
- The kind of roast, the brewing technique, the amount of ground coffee that a person uses throughout the brewing process, and the serving size are all important considerations when making coffee.
Despite the fact that coffee is arguably the most well-known source of caffeine, this chemical may be found in a variety of different foods and drinks. The FDA, on the other hand, does not compel manufacturers to indicate the amount of caffeine included in packaged foods, drinks, or dietary supplements on their products. Below, we’ll go through some of the other popular sources of caffeine:
Tea
Various types of tea contain various amounts of caffeine, although the quantity in a cup of tea is normally less than in a cup of coffee of equal size. For example, an 8-oz cup of green tea has around 28 mg of caffeine, but the same serving size of black tea contains approximately 47 mg of caffeine (see chart).
Soft drinks
Soft drinks, such as sodas and fruit-flavored beverages, may contain small amounts of caffeine from time to time. For example, a 12-ounce can of Coca-Cola has around 33 mg of caffeine on average.
Energy drinks
Energy drinks can include extremely high concentrations of caffeine and sugar. Caffeine can come from a variety of sources, including synthetic and natural ones such as guarana leaves. It is important to note that the caffeine level of energy drinks varies greatly between brands. According to the Food and Drug Administration, the caffeine level of these beverages normally varies between 40 and 250 mg per 8 oz serving. Some energy drinks, on the other hand, can contain as much as 316 mg of caffeine per 8 oz serving.
Chocolate
Caffeine is naturally found in chocolate, however the quantity varies depending on the amount of cacao in the chocolate. Caffeine content in darker chocolate is often higher than that of lighter or milk chocolate. To give you an example, the caffeine content of a 1-ounce portion of chocolate is as follows:
- 45–59 percent cacao solids: 12 mg
- 60–69 percent cacao solids: 24 mg
- 70–85 percent cacao solids: 23 mg
- 90–100 percent cacao solids: 24 mg
Medications
Several over-the-counter and prescription drugs include caffeine, which can help to alleviate pain more effectively. Examples include Menstrual Relief Maximum Strength, which contains 500 mg acetaminophen, 15 mg pyrilamine maleate, and 60 mg of caffeine in a single capsule. Adults should drink no more than 400 mg of caffeine per day, according to the Dietary Guidelines for Americans 2015–2020 dietary guidelines. According to the Food and Drug Administration, there are no specific recommendations for children, however the American Academy of Pediatrics discourages children and adolescents from using caffeine.
They also caution that caffeine may have a greater effect on youngsters under the age of 12 because they tend to weigh less than their older counterparts.
Caffeine is usually considered to be harmless for the majority of individuals when consumed in moderation. Caffeine, on the other hand, might have negative side effects when used in excess. The following are examples of adverse effects:
- Headaches, feeling restless or jittery, nervousness, anxiety, irritability, tremors, fast heartbeat, problems sleeping or sleeplessness, upset stomach, nausea, diarrhea, and frequent urination are all possible symptoms.
The amount of caffeine contained in a cup of coffee can vary significantly. The brewing process, the kind of bean, and the quantity of coffee grounds that a person uses are all factors that influence the caffeine level of a cup of coffee. A standard 8-oz cup of coffee has around 80–100 mg of caffeine, although other coffee beverages can have substantially more caffeine than this. Besides coffee, energy drinks, soft drinks, chocolate, and various pain relievers are all high in caffeine as well.

Tip
There is no straightforward answer to the question of how much caffeine is in a cup of coffee. Exact quantities vary depending on the type of beans used, the method of brewing, and the length of time the beans are roasted. The amount of caffeine in a cup of coffee varies depending on the type of bean used to brew it, as well as the style of coffee drink you choose to consume, which can range from a conventional brew to an espresso, an instant, or a decaf cup of coffee.
Consider the Caffeine in Coffee
When you prepare a cup of coffee, the quantity of caffeine in it will vary depending on how strong you want it to be. According to a 2017 paper published in the journal Journal of PsychologyPsychotherapy_, a cup of coffee contains around 100 mg of caffeine on average. Instant coffee has a bit less caffeine, with around 80 mg per cup. When compared to tea, which contains 30 milligrams of caffeine, instant coffee contains 60 mg. A can of Coke contains around 34 mg of caffeine on average. You will get more caffeine in your eight-ounce cup of coffee if you like lighter roasts as opposed to darker roasts if you prefer lighter roasts.
Additionally, there is a significant variance in the beans that are utilized.
According to a report published in August 2016 by the European Food Research and Technology journal, Robusta coffee beans generally contain around double the amount of caffeine found in Arabica beans.
Compare Coffee Types
In addition, there is a variation in caffeine content between conventional brews, espresso, instant coffee, and decaffeinated coffee. According to the USDA, if you prepare ordinary instant coffee, you’ll get 28.3 mg of caffeine per one teaspoon of dry grounds. A shot of espresso in your coffee on those days when you need that extra kick can provide you with an additional 63.6 mg of caffeine from just one ounce, according to the US Department of Agriculture. There is even a little amount of caffeine in decaf coffee—2.4 milligrams per 8-ounce cup—which is beneficial to your health.
Know Your Limits
The Mayo Clinic claims that 400 milligrams of caffeine per day is typically safe for most healthy individuals, despite the fact that everyone is different and some people can tolerate more caffeine than others. Having a little caffeine in your diet is totally OK, but too much caffeine can cause your heart beat to become erratic, make you dizzy, cause headaches or heartburn, and cause you to get dehydrated. Be aware of some of the adverse effects of caffeine, and reduce your intake if any of them begin to have a detrimental influence on your well-being.
